Canada

Actually, it was the Canadian soldiers that marched through Italy; the Canadian soldiers that marched north to Denmark and protected the American flank; the Canadian landing at Juno beach which not only protected the American flank, but pushed further and faster, greeting the American troops as they finally pushed off of their beachhead; the Canadian top command that developed the more efficient ways of fighting a modern battle, especially the results learned from the essentially Canadian Dieppe raid (which WAS successful, the Canadians got off the beach and made it to the post office for what they went for); the Canadian scientists that worked on the development of the Atomic bomb long before the Manhattan Project, and went on to establish Chalk River; the Canadian merchant marine that kept Britain supplied during the war... the list goes on and on. You do not need to be a tankie, just a good student of Canadian history.

Unfortunately for our Canadian legacy, we do not brag.
